@ Tips
The ill umi nat ion fo r th e i nstru me nt cl uster
lights up whe never yo u switch on the i gni ­
tion with t he
vehicle headlights off . As
the daylight fades, the instrument cluster illumi nat ion likewise dims automatically
a n d w ill go out completely when t he out­
side light is very low. This feat ure is meant
to remind you to switch on the headlights
w hen o utside lig ht con dit io ns become
poor.
Engine coolant temperature gauge
The eng ine coolant gauge q page 10, fig. 3 CD
only works when the ignition is on. To p revent
damage to you r engine, please note the fol­
lowing impor tant po ints:
Engine cold
As long as the needle remains at or close to
the bottom of the gauge, the engi ne still has
not reached its operat ing temperature . Avoid
high eng ine speeds, heavy eng ine loads and
heavy th rottle a pplicat io ns.
Normal temperature
When the engine has reached its operat ing
temperature, the needle w ill move into the
midd le of the gauge and rema in the re. If th e
engine is worki ng ha rd at high outside tem­
peratures, the needle may rise up. This is no
need to worry as long as the. warni ng lig ht
i n the i nstr ument cluster does not ill uminate.
Warning light in the instrument cluster
When the. warning lig ht in the instr ument
cluster s tarts to flash, th is can mean one of
two things : either the coo lant
temperatur e is .,..

too high, or the coolant level is too low
¢ page 32.
If the needle is well in the upper area of the
ga uge , the coolant temperature is too high.
Stop the vehicle , switch the eng ine off and
allow the engine to cool.
If the warning light
comes on again after driving a short distance,
contact an authorized dealer.
A WARNING
- Always observe the warning in
¢
page 256, before opening the hood
and checking the engine coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dr ipping from the engine compartment.
You could bu rn yourself. Let the engine
cool off first until you can no longer see
or hear steam or coolant escaping.
0 Note
- Mount ing additional lights or accessories
i n front of the a ir inlets reduces the cool­
i ng effect of the radiator. At h igh outside
temperatures or high eng ine load , the
engine could overheat.
- The front spo iler has been designed to
properly distribute the cooling air when
the veh icle is moving. If the spoiler is
damaged, this cou ld reduce the cooling
effect and the engine could then over­ heat. Ask your authorized Audi dealer for
ass istance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
The tachometer @¢ page 10, fig. 3 is the left
of the two large clock-type displays.
The engine turns at a speed 1,000
times the
single digit in the display, e.g . if the needle is
pointing at the "2" the engine is turning at
2,000 RPM.
If engine RPM drops be low 1,500, you should
downshift to the next lower gear. The red area at
the end of the scale indicates maximum
permissible engine RPM after the break-in pe­
riod. Before reaching this area , move these­
lector lever to position D (Drive) or ease your
foot off the accelerator pedal.
(D Note
The tachometer needle should not move
into the red range. If it does, then only for
a very short per iod of t i me. You could
damage your engine by driving at high RPM .
@) For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise .
Digital clock with date display
Fig. 4 In st ru m en t cluster : time a nd da te
The date, time of day, and time and date for ­
mat can be set in the MMI. You can learn more
about this in the MMI manual.
(D Tips
-When open the driver door, the time,
date and odometer are disp layed for an
add itional 30 seconds.
- You can also call up the display with the
!CHECK I button q page 12 while the ig­
nition is sw itched off.

12 Instruments and warning/indicator lights
Speedometer with odometer
The speedometer shows you the vehicle
speed, and the odometer shows you how
many miles (kilometers) you have driven.

You can switch the display from miles to kilo­ meters and vice versa via the MMI. You can
find out more in the MMI manual.
Lower odometer
The lower odometer shows the total number
of mi les (kilometers) driven.
Upper odometer (trip odometer)
The upper odometer shows the tota l number
of mi les (kilometers) driven since you last re­
set the odometer to zero. You can use this od­
ometer when you want to keep track of how many miles (k ilometers) you have driven for a
single trip or errand. The last digit indicates
1/10 of a mile (100 meters).
You can reset the trip odometer to zero by

Ci:> Adaptive Air Suspension
A ppl ies to vehicles: with Ada ptive Ai r Susp en sio n
This II warning/indicator light has the fol­
l owing f unctions:
- It illuminates for a few seco nds after the ig­
nition is t urned on as f unct ion check and
then goes out . -
If the warning/indicator light illuminates or
blinks contin uously, there is a system fault
in the Adaptive Air Suspension. A system
fau lt can result in lim ited ride comfort and
lo w ground clea rance . Drive safely to the
nearest authorized Audi dealer or qualified
wo rkshop, and have the fault corrected.
- If the warning/indicator light flashes, you
should not dr ive the veh icle . The flashing
warning/indicator light points to an extreme H igh level. A very
pronounced lifting of the
veh icle (ext reme H igh leve l) can result, for
examp le, when a heavy load is removed
from the vehicle. As soon as the level has re ­
t u rned to norma l, the wa rning/indicator
light stops flashing, and you can drive away.
- If the warning/indicator lig ht flashes in con ­
junction with the. warning/indicator
light, you should not dr ive off immediately
in order to prevent damage to the under­
body. The two warn ing/ indicator lights
flashing together points to an extreme Low level. A ve ry
pronounced lowering of the ve­
hicle (extreme Low leve l) can result, for ex­
ample, from a heavy load. As soon as the
level has retu rned to normal, the warn ing/
ind icator lights stop flashing, and you can
drive away.
